440ea43a88 z80a: make mnemonic names more uniform across assemblers
Initially, I used the same letters as those used in the z80 ref
docs, but it makes the different assemblers harder to use than they
should. Having consistent "argtype" rules across assemblers should
help.

dbd283758c Refer to BOOT and (uflw) by addr in stable ABI
Was previously referred to by name+find, which was wasteful.

035532acf7 z80: remove remaining indirections in execute calls
We now have a stable ABI that is pretty cleared up...

3d2dc041fb Make word routines into word types
Instead of having wordref point to core word routines, I made them
into word 4 word types. It liberates space into the stable ABI and
should make porting to other arches easier.

I'm also thinking of combining word type with the namelen field
for precious bytes saving, but not now...

ea9833d4ff Remove LITA
It was useful when we still had the relinker, but now it has no use.
I was waiting a bit to see if the distinction would be useful again,
but it seems like it won't.

40f92b9bab z80: optimize chkPS
Inline it in next and make chkPS, call a newly reserved label for
it directly, removing a layer of indirection. This frees a spot in
the stable ABI.

f6ded7712e VE: add 't'
This is the first commit I do entirely in VE. It's a habit I'm planning
on taking as it helps a lot to find usability issues.

3fbae082f4 Remove INTJUMP mechanism
Not worth the trouble. Easier to set jump in binary directly.
